Spammers Away

So for the last few months I've been recieving Spam Comments that lead to dubious Links mostly in a Chinese/Japanes language. You think one would be thankful at even being left spammed comments but no I'm definately not. If you read any that I have yet to delete please do Not click on of the their hyperLinks I try to inform Blogger everytime that one appears and report them but at the moment it is really a pain to keep up. I wish I could disable them but that would mean removing it all together and I want this an open forum already I have had to remove Anonymous comments. Any Ideas on better security would be greatly appreciated.
